Programmable Logic Controller based on reconfigurable logic

The paper presents an idea of a Programmable Logic Controller for binary control implemented in an FPGA device with use of custom designed implementation tools. It is an extension of previously proposed architecture that is mainly limited by hardwired connection. Based on connection resources available in FPGA the new architecture is proposed. Possible computation capabilities of FPGA devices are discussed. The research task is continued and looking for nonmultiplexed solution with extended usage of programmable connections and better exploit of logic resources.
